Dammit!!!! Out of nowhere, I started my truck and began driving to the end of the street. Stopped at a stop sign, and there it was. That tiny little whirring sound. I figured the belt, but nooo. No it's never the cheap alternative. Went back home, got a stethoscope and put it to each pulley. And I'll be damned if my water pump is going out. Took the belt off, and I can wiggle the pump and pulley easily. Since yesterday, its gotten horribly loud, but my engine stays at normal engine temperatures. Time for a new one! Wish me luck that she'll last until Thursday so I can get off work and rip her apart and put in a new one. Any advice on water pump brands to go with or stay away from?

 

I have the same problem, but my water pump has 8K on it and its brand new, not a reman, or used. sprayed some WD40 on the pulley, and it took care of it.

 

I sprayed some WD-40 on it as well, and it got quiet for a few seconds, and suddenly it got even louder. I have no idea why it got quiet, but it does every time I spray it. It just gets louder after a few secs

 

alright since you eliminated that, and you said you have a wobble, then yes its time to do the water pump.

when you do it, get a new thermostat and bypass hose.

then to bleed the cooling system (since they can be a pita)

1. jack up pass. side so that the radiator cap is the highest point.
2. fill the radiator until full
3.put the heat on full blast/defrost then start the truck
4. add coolant accordingly.

 

if your plenum's never been fixed, while doing the water pump is a good time

 

get a new belt too of you getting any coolant on it.. or it's leaking on the belt

 

Yea, I'll get a new belt, go ahead and do a radiator flush, and I'd short on time and money, so I'm not going to worry about the plenum right now. I plan on purchasing the Hughes Air-Gap in the near future. If anybody remembers my post about my "engine too cold for too long", since I replaced my thermostat (195) and flushed my radiator, think it could be my pump thats still causing the problem? My CEL doesnt come on anymore since I removed the PowerWire, but my temperature is still well below normal...

 

might as well flush your heater core too

 

Well, flushed the radiator, got some new hose clamps, installed the new water pump, and the noise is gone. It seems like I have better throttle response too. Maybe my bad water pump was putting alot of drag on my motor?

 

Don't fell like the lone ranger, I just did mine too. Funny thing is, it sound like rattling beer cans and ran that way for a year. When I pulled the WP I found the impeller had been hitting the casting. No leaking but the bearing was out. Gotta love your Dodge!
